Excerpt from Fungous Diseases of Plants With Chapters on Physiology, Culture Methods and Technique
It is a noteworthy fact that there has been available to student and reader no general text or reference book of American origin upon fungous diseases of plants. Nevertheless, for thirty years or more there has been active investigation in this field, and during much of this time instruction in plant pathology has been an important part of biological teaching in all colleges where plant industry or country-life interests have been adequately represented. In the agricultural colleges the teaching of general mycology has been important, and that of plant pathology is now essential. The presentation should be fundamental, but it should also bear a close relation to the affairs of life. Plant pathological work has been rapidly developed in all countries characterized by a progressive agriculture, and for European conditions the student experiences no great lack of reference works.
Through the agricultural experiment stations and through the extension work in various states a vast amount of information with respect to plant diseases has been published and otherwise disseminated, so that to ever) intelligent plant producer the opportunity has been extended of becoming more familiar with the crop relations of destructive parasitic fungi. The student and the progressive grower require something further, and it has therefore seemed none too early to put in book form a comprehensive discussion of the chief fungous diseases of cultivated and familiar plants. It is not intended that this book shall be an introduction to systematic mycology; yet the arrangement of the material in taxonomic sequence with respect to the fungi largely eliminates the necessity of any mycological preparation as a prerequisite.
